A Microprocessor Based 16 Channel Datalogger

Abstract

This report describes a 16 channel voltage recording instrument designed for use in optical radiometry, but with applications in other fields. The 16 channel datalogger provides a means of connecting a radiometer, consisting of 16 silicon diodes with appropriate filters, to a Hewlett-Packard 97S printing, programmable calculator. On command, the datalogger simultaneously samples and stores the 16 input voltages, and supplies the values and corresponding channel numbers to the calculator, to allow recording using the inbuilt printer. The calculator can be programmed to control how often samples are taken, and it can also perform numerical manipulation of values for calibration or scaling, before printing. The datalogger can display the stored voltages on an inbuilt LED display, and can also display input voltages in real time, while samples are not being taken.
